Thrombosis in the critically ill neonate: incidence, diagnosis, and management

Area of Science:

• Neonatology
• Pediatric Thrombosis
• Critical Care Medicine

Background:

• Newborn infants, especially critically ill term and preterm neonates, are highly susceptible to thrombosis and thromboembolic complications.
• Key risk factors include inflammation, disseminated intravascular coagulation (DIC), liver dysfunction, hemodynamic instability, congenital heart disease, and indwelling catheters.
• Thrombosis in neonates can be symptomatic or asymptomatic, detected through screening or incidental imaging.

Purpose of the Study:

• To review the pathophysiology of neonatal thrombosis.
• To outline diagnostic methods for neonatal thromboembolic disease.
• To discuss acute and long-term management strategies for thrombosis in critically ill neonates.

Main Methods:

• This is a review article synthesizing current knowledge.
• Information was gathered on pathophysiology, diagnosis, and management of neonatal thrombosis.
• Focus is on critically ill term and preterm neonates.

Main Results:

• Diagnosis commonly utilizes ultrasound, venography, CT, or MRI angiography.
• Acute management options range from observation and anticoagulation (heparin) to thrombolysis and catheter-directed revascularization.
• Long-term anticoagulation is often unnecessary after patient stabilization and catheter removal, but may be indicated for congenital heart disease or inherited thrombophilia.

Conclusions:

• Neonatal thrombosis requires careful diagnosis and tailored management based on individual risk factors and clinical presentation.
• While many neonates improve with supportive care and catheter removal, specific conditions may necessitate long-term prophylactic measures.
• Understanding the pathophysiology and diagnostic modalities is crucial for effective treatment and improved outcomes in critically ill neonates with thromboembolic events.
